SEALING ATTACHMENT FOR FRUIT-JARS.

Specification of Letters Patent.

Patented July 13, 1920.

Applicationiiled' April 15, 1920. Serial No. 374,017.

To all whom it may concern Be it known that I, WILLIAM H. F. YOUNG, a citizen of the United States, resid ing at Muncie, in the county of Delaware and State of Indiana, have invented certain new and useful Improvements in Sealing Attachments for Fruit-Jars, of which the fol lowing is a specification, reference'being had therein to the accompanying drawing.

This invention relates to improvements in sealing attachments for fruit jars, and is particularly designed for use in connection with glass fruit jars.

The primary object of my invention is to furnish an attachment for jars which holds the jar cover under spring-clamped tension against a suitable packing, whereby a tight closure is insured for excluding air from the ar. J A further object of'my inventionis to provide an attachment for 'jarswhich comprises two members which extendover and engage the jar cover, a coiled spring having one end engaging one of the said members, a screw bolt passing throughthespring and having one end connected with the other member and the opposite free endofthe bolt carryingan adjustable nut 'for compressing the spring and drawing the ment bers tightly against the top of the jar under spring tension. 1

'A further object of my invention is to pro- I vide a closure attachment for jars WVlllCh utilizes two loops that extend up over the top of the cover of the jar, a' horizontally extending bolt having one end connected' with one of the loops, a'coiled spring surrounding the bolt and having one end connected with the other loop, the free end of the bolt being screw-threaded and carrying a nut for forcing the spring along the bolt and causing it and the bolt to draw the loops under spring tension against the top of 'thecover and hold it tightly with spring tension against a suitable packing between the cover-and the mouth of the jar.

- Further objects of my improvement will appear from the following description and drawings. f it 1? In the accompanying drawings-- Figure 1 is a perspective'vi'ewfof the upper endof a jar, showing my improvement applied thereto.

- Fig. 2 is a side elevation of Fig, 1, the j al being shown partly in section.

Referring now to the drawings, 1 is a jar having the usual mouth 2. This mouth is provided with a shoulder 3, upon which rests asuitable packing ring preferably rubher, and is the. cover.

My improved sealing attachment comprises two loops 6 and 7, which are approximately triangular in outline The lower ends of these loops 6' and 7 are provided with suitable hooks or'eyes 8, which pass through eyes 9, formed in a wire ring 10.

This wire ring 10 has its ends-11 twisted together, whereby it is adapted to be applied under the usual shoulder 12 below the end of the mouth of the jar.

The upper'end or apex ofthe loop 6 is provided with a vertical eye 13, formed by one or more coils. A bolt 14 has oneend bent downward, as at 1 5-, and passes through the eye 13 and is-suitably headed as at 16. The bolt14: extends horizontally across the cover 5, as shown, and isprovided with screw'threads 17 extendinga suitable distance throughout its length.

A coiled spring 18'surrounds thescrew threaded part of the bolt 14,- and has its inner end 19 bent outward longitudinal its coil and provided at its extremity with a hook 20, which passes through a horizontally arranged eye 21, which is formed at the upper end or apex ofthe loop A thumb-nut 22 is placed on the screw threaded end of the bolt 14 and engagesthe outer end of they coiled spring 18.

-The loops 6 and? cxtend 'upward and.

curve inward over the cover 5 and engage it to press it down for forcing the edge of the cover against the packing 4c, andcompress :ing it and'making ita tight closure.

f. The coiled spring 18 is-of the! expanding type. That is to say when not compressed by the screw nut 22,'the coil expands, but

the expansion is less than the adjusted outer movement of the nut 22 on the bOlt'll.

In Figs. 1 and 2, the jar'andthe attachment are shown in their-closed positions.

'The nut 22 has been turned inward on the bolt'lt, compressing the coiled spring 18 and causingits hooked end 19 and the end 15 of the bolt to pull the upper ends of the 1001956 and 7 toward each other andforcing them down onthe top rand in turn forcing the top 5 down tightly against the packing ring 4, and compressesit to make a tight joint; By turning the nut 22jupwardon' the bolt, the tension of the'spring will be '7 7 released and the hook 20 can be disengaged from the eye Ql'and the bolt and loops 6 and 7 turned away fromthe' jar cover 5,to permit it to be removed to have access to the ar to fill it, or to remove anything from the jar. The ar can be again closed by swinging the loops'inward and causing the hook 20 to engage the eye 21 and then turning inward on the nut 22. s

In this way the jar can be quickly and tightly closed or quickly and conveniently opened.

This invention can besold as an attachment to be attached to :jars audit is designed so that it can be so sold andattac'hed to ars. Iii-this event, ofcourse,'-the ends 11 of the ring 10 are not twisted'together until the attachment is applied to the jar. "On

' the loops 6 and 7 should extend over and engage the cover, when they are drawn to gether z-by compressing the spring on the bolt 14; 'The spring 18--is forced endwise on thebolt, as it is being compressed and draws the loops toward "each other, for forcing the cover down. Y

I do not limit my invention to" the exact details'of'construction here showmior variations may be madeinthem,without"departing from the scope and spirit of theJlnvention, as defined in the following claims.

Having thus described my invention what I claim and-desire to secure by LettersPatv :ent is;; Y
